CMMVC8668E The host mapping was not created because the SCSI logical unit number (LUN) ID is not valid for this particular host type.
Explanation
An attempt was made to create a mapping between a volume and an adminlun host, but the SCSI LUN ID is not within the range for adminlun hosts. The highest SCSI LUN ID that is permitted for an adminlun host is 512.
User response
Retry the command with a valid SCSI LUN ID.
